Introduction

GMRT consists of 30 antennas spreading over an area of 50 square kilometers. All the Antenna Shells are equipped with various intelligent sub-systems for providing the best results to this Radio Observatory. Hence it is a prime responsibility for providing safety and protections to all these sub-systems especially in the remote antenna shells from intrusion, fire, smoke, over temperature etc. All these parameters are getting monitored from the remote antenna shells to the Control Room all around the clock. GMRT Sentinel System is taking the full responsibility for monitoring and controlling the above parameters for smooth operation of GMRT.
